CHARLES C. RIT'IENHOUSE, OF LOS ANGELES, CALIFORNIA.

ELEVATOR.

To all whom it may concern:

.-'Be it known'that I, CHARLES C. RITTEN- noose, a citizen of the United States, residmg at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Elevators, of which the following is a specification.

The object of my invention is to provide safe, sanitary, convenient and speedy means to remove to or from the rooms of an apartment-house having a number of floors, different articles that are required to be taken to or from these rooms. This is accomplished by means of the apparatus described herein and shown in the accompanying drawings, in which:

Figure 1- is an elevation showing parts of my improved elevator inplace in an apartment-house, and showing also the different doors forming closures for the open ings leading from the different rooms into the elevator shaft. Fig. 2 is a vertical transverse section showing the various carriers in place on the cable in the elevator shaft. Fig. 3 is a side elevation of the pulleys, weights and cables, parts of the elevator casing being broken away for purposes of illustration. Fi 4 is a transverse section of the elevator shaft showing a plan view of the carriers in place in the shaft. Fig. 5-is a perspective view of one of the carriers removed from the cable and a fragmentary view of the elevator cable with the carrier clamps secured thereon, disclosing the means of detachably securing the carriers to the cable. Fig. 6 is an enlarged detail of the winding drum, the cable thereon, the ratchet holding mechanism and the operating crank. Fig. 7- is an enlarged detail of the ratchet mechanism. Fig. 8 is a central vertical section of two carriers in place on the cable. Fig. 9 is a perspective View of the casing for the elevator shaft.

This application is for a patent on an improvement on my elevator as shown in U. S.

cured at properly spaced intervals along the Specification of Letters Patent.

elevating cable and adapted when in place on the cable to register (one for each room) with the openings leading from the various rooms on the different floors of the building when the cable is in its normal position.

Patented Aug. 9, 1910. 1'

These carriers, numbered 41 in the ac'comj panying drawings, are divided into an upper and a. lower compartment, one of the compartments being water tight for the reception of garbage and waste material which may be placed therein, the other compartment being adapted to receive and carry any article to the room from the basement or from the room to thebasement.

In the drawings, 9 represents the walls of the building in which the elevator is placed and 39 represents the doors closing the openings leading to the elevator shaft from the various rooms. In the basement 10 is mounted a rotatable drum 11, around which passes in frictional engagement the operating cable 12. This drum is operated by the crank 13. In this case I have shown the elevator installed in a building containing three stories in addition to the basement. In the top of the building above the upper floor is mounted a cable supporting pulley 14, around,

downwardly around the idler or pulley 28 and thence extends upwardly and at its other end is secured to the under side of the block 27. A carrier-supporting cable 40 is also secured to the under side of the block 27 and drops downwardly therefrom as shown in Fig. 3 to a convenient point which may be about on a level with the winding drum (see Fig. 1) and turns at this point upwardly and is secured to the cable 12 at the point 31 (Figs. 1 and 3). Disposed along and secured at proper intervals to this cable 40 are the carriers 41. By this arrangement it will be manifest that this cable 40 which carries the carrier securing clamps will never pass over any pulley. On, the top of this block 27 are secured two counter-weight supporting cables 32 which extend from the block upwardly and pass over the two idlers 29 and drop down to a point near the bottom of the shaft as shown in Fig. 3 and carry at their bottom ends the counter-weights 15. These counter-weights are made up of different integral parts so that by removing or adding these parts, the counter-weights may I be made lighter or heavier as desired, so as to form a proper counter-balance for the different carriers and their contents secured on the carrier-supporting cable. lVhen the. counter-weights are at the highest point in the shaft to which they move, the clamps for the carrier serving the top room will be in the basement and the clamps for securing the carrier for serving the lowest one will be at the top of the shaft.

In Fig. 5 I have shown means whereby these carriers may be detachably secured at proper intervals to the cable as follows; each carrier is provided at its top with a hook 16 adapted to enter an opening 17 in the clamp 18, which clamp is secured to the cable by bolts On the bottom of the carrier l have mounted a bifurcated bracket 19 adapted to straddle and rest on the clamp 20 on the cable, this clamp being provided with indentations 21 for the reception and engagement of the bifurcations 22 on the bracket 19. This will provide means whereby the carriers may be readily placed on or removed from the cable.

Assuming that the carriers are in place on the elevator cable and it is desired to remove the contents from the various carriers or to remove articles from the basement to the various rooms or both, the handle 23 of the crank is grasped and the ratchet dog 2% moved out of engagement with the ratchet teeth and the carrier-supporting cable l0 permitted to descend. XV hen the carrier adapted to serve the first floor has arrived at the basement or platform provided therefor, the carrier is removed from the cable. The carriers are then again permitted to descend until the carrier adapted to serve the second floor has descended to the basement platform when it is removed, and so on until all of the carriers have been removed from the cable, at which time the counterweights will have moved to the highest point in the shaft. After the contents of the various carriers have been removed therefrom by the janitor or other attendant, the articles to be conveyed to the various rooms above will be placed in the proper carriers, and the carrier adapted to serve the upper story will be first put in place on the cable. The handle 23 is then grasped by the attendant, the ratchet dog 25 is removed from the ratchet wheel 26 and the crank is rotated until the clamps on the cable adapted to receive the carrier for the second story from the top is in place in the basement when the carrier for the second story from the top is secured on the cable, when the cable is again elevated in like manner until the clamps for the engagement of the carrier for the third story from the top is in place in the basement when the carrier for that floor is placed thereon, and so on until all of the carriers eeav'ee for the various floors are in place on the cable, when they are all elevated into place and register with the various openings leading from the shaft to the respective rooms. The elevator is permitted to remain in this (its normal) position with the various carriers in register with the openings leading from the anions rooms until a certain predetermined time when the elevator is again operated as hereinbefore explained. In the arrangement herein shown I have adapted this carrier so as to serve two tiers of adjoining rooms, thereby lessening the number of elevators required to do the work.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A flat elevator, comprising a wall of the flat having a shaft therein, cables in said shaft, carriers thereon spaced apart to register with openings leading from the shaft to rooms alining said shaft, means to counter-balance said carriers and contents contained therein, means to hold said cables against movement in either direction when the elevator is at rest, and means to operate said cables.

2.
